how to configure the adc internal reference voltage??
Hi team, I am using STM32L052K8U6 package in my design. I need to configure the internal reference voltage instead of external reference voltage for ADC. Can i get any example program for same.

Resolved! why i couldn't receive continuous data of GPS over UART?
Hi,I am trying to get the NMEA data over UART and print it over another uart .But when i try read in loop after writing data to PC ,I'm not receiving any data. what could be the issue?any ideas ??
Is it possible to monitor the file copy status by the program in MSC mode? Like file copy from SD card is in progress, file copy completed etc? If yes, what is the method?
I am using stm32 L4 family microcontroller. I enabled MSC mode to copy files from SD card mounted to device to PC. But I want to know how can I monitor the status from my code running in MCU? My program should check whether file copy in progress, com...
SPI recieve over DMA works only once in stm32f103 on HAL
Hello. I'm trying to receive data from W25Q128 via SPI. It works good, but too slow, if I don't use DMA. If I'm using DMA, it works faster, but only once, second query doesn't return data.I'm reading flash in main loop once in second this way, when d...
Resolved! STM32 controller -0.4V to 3.6V ADC converter
Hello,for an upcoming project I am searching for a low-power microcontroller with a rich peripheral set and the possibility to sample low frequency signals in the range from -0.4V to 3.6V .As far as I have looked it up I will have no chance realising...
Implementation of double buffer mode in USART-DMA in stm32f7
Hi,i want to implement double buffer mode in USART-DMA(STM32F7) .is there any example programs available with double buffer mode??Thanks in advance
SPI slave mode. Getting Started.
I'm in the early stages of a project involving SPI. I need to send data to an stm32f303, from an rPi.I also need to detect, from the rPi, a GPIO based interrupt to then go read from the stm32.rPi is master, stm32 is slave.Can anyone recommend a helpf...
Resolved! Non-blocking SDIO SD Access - SDIO Timeout
I've been working on making my SD SDIO card access non blocking. My implementation is a derivative from the standard ST SDIO SD driver (stm324xg_eval_sdio_sd).I'm using Protothreads (basically a state machine) to make the SD SDIO calls non-blocking a...
STM32H7 and QUADSPI external flash reading problem - One byte every two is skipped
Dear all,I am trying to communicate to a flash memory using the STM32H750 micro and its QUADSPI interface. For this I use the STM32H750B-DK Discovery board which provides a dual external flashmemory (MT25QL512). In my first example I am just trying t...
STM32F750Z8 and flash loader
Hello everyone,I've just develop my board with this MCU and a QSPI Flash from Micron (N25Q128).The connections suggested by the Cube are:CS -> PB6CLK -> PB2D0 -> PF8D1 -> PF9D2 -> PE2D3 -> PA1Checked them and they are phisically good.I'm using IAR so...
